Patented May 26, 1931 UNITED. STATES PATENT OFFICE ERWIN SCHLIEYHAKE, OF JENA, GERMANY Application filed July 18, 1930, Serial lie. 468,821, and in Germany July 25, 1929.

In order to carry through an eflicacious diathermic treatment by means of hi h frequency in the field of the condenser, 1t is of advantage to concentrate the energy on cer- 6 tain points. As it is not possible to introduce perhaps an electrode of the condenser into the human body and the other electrode externally thereof, it is suggested according to the invention, to place the part of 10 the human body to be treated into a condenser and to provide a mass of metal in the field of the said condenser, which will cause the field lines of the condenser field to be drawn to the mass of metal and in consequence the parts close to it will be subjected to a stronger heating than would be the case with a condenser field of the customary type.

In order to give a practical example, or instance probes or bougie-pipes may serve as metal mass to be introduced into the respective cavities of the human body, as for instance, the stomach, nose, ears and wounds. For the treatment of alveolar abscesses metal plates of suitable form are placed into the mouth of the patient. These probes necessarily need not consist entirely of metal, but it will be advantageous to make these substantially of some insulating material and to provide them with corresponding metal inserts, in order to avoid scorching of the parts of the body with which they are in contact.

An embodiment of the arrangement according to the invention is shown in the drawing by way of example, purely diagrammatically.

Both the condenser plates K and K are located in a circuit coupled with the generator of the hi h frequency oscillations. On the surfaces acing the body of the atient these plates are preferably provide with coatings J and J 2 of some suitable insulating material. The probe S surrounded by insulating material is introduced into the body of the patient.

I claim:

Apparatus for diathermic treatment by means of'high frequency of the character described com risin a condenser, two condenser electro es of fit rger size and a smaller signature.
